Koyambedu Tertiary Treatment Reverse Osmosis (TTRO), Chennai, India
Water Recycling and Reuse Plant Delivering High-Quality Industrial Water for Chennai
The 45,000 m³/day Water Recycling and Reuse Plant at Koyambedu is a landmark project enabling Chennai to convert secondary-treated municipal wastewater into high-quality reclaimed water for its industrial hub in South Chennai. Delivered under a long-term Design-Build-Operate framework, the facility ensures a reliable supply of treated wastewater reuse, supporting one of India’s largest auto manufacturing clusters.
Tertiary Treatment Reverse Osmosis (TTRO) Plant Ensuring Superior Water Purification
The water recycling and reuse plant integrates advanced tertiary technologies such as Dual Media Filtration, Ultrafiltration, Reverse Osmosis, and Ozonation. This multi-stage process guarantees high-purity water suitable for industrial applications, significantly reducing industries’ dependence on freshwater sources while meeting international water-quality benchmarks.
Municipal Wastewater Reuse Strengthening Chennai’s Industrial Growth
Secondary-treated wastewater from the Koyambedu municipal wastewater treatment plant is transformed into reclaimed industrial water through a robust treatment sequence. With its dedicated 68 km transmission pipeline, the water reclamation plant supplies high-quality water directly to the Southern Industrial Hub, ensuring continuous operations for major manufacturing units and supporting long-term industrial expansion.
A Leading Water Recycle and Reuse Plant Advancing Circular Economy Goals
As one of the most technologically advanced Tertiary Treatment Reverse Osmosis (TTRO) plants in India, the facility demonstrates innovation in treated wastewater reuse and strengthens WABAG’s leadership among global water recycling companies. By saving over 13,000 million litres of freshwater every year, the project showcases a sustainable, circular model for future-ready urban water management.
